ETI Circuit Breakers

ETI breakers and DIN modular devices represent a flexible, high-performance line of eti modular devices, eti din modules, and eti electrical protection devices. Engineered in Europe under strict quality control, these devices form the critical protection layer in low-voltage power distribution and control systems. They are designed to work reliably under thermal stress, switching cycles, short-circuit conditions, and comply with IEC / EN norms. As procurement specialists, you’ll appreciate that the etigroup brand supports clear traceability, modular expansion, and compatibility with standard DIN-rail architectures.

ETI offers a broad current range (from fractional amperes up to tens of amperes in modular format, and much higher in MCCB classes). Their devices include miniature breakers, overcurrent protection modules, residual current breakers, and multi-function units, making eti modular protection devices a versatile toolset for industrial, commercial, and residential applications.

ETI DIN Modular Breakers — Core Range and Functionality

The heart of the ETI modular lineup is its eti din circuit breakers and eti miniature breakers. These are compact, modular units designed for installation on standard 35 mm DIN rails, with widths measured in modules (e.g. 1, 2, 3, 4 modules). They accommodate single-pole to multi-pole configurations. Their thermal-magnetic tripping elements protect against overload and short circuit events, and their rugged architecture supports frequent switching operations.

These eti din modules are engineered with arc chambers, high-conductivity contact materials, and carefully designed internal geometry to limit temperature rise. Engineers choose them based on rated current (e.g., 1 A to 63 A typically) and predetermined breaking capacity (often up to 6 kA or more in modular class). Their modular nature allows snapping into compact distribution boards. In wholesale orders, products are packed in standard multiples, each labeled via EAN / MPN so buyers can import into procurement systems cleanly.

ETI Modular Protection & Overcurrent Devices

Beyond standard breakers, ETI extends its portfolio to eti modular protection devices — including RCCBs, RCBOs, and surge protection modules. The ASTI line for modular current and residual protective devices is a key example.RCBO (residual current with overcurrent protection) units combine multiple protection functions in one module. These devices allow efficient use of space in panels, and reduce component count. Their performance is rated over temperature ranges (–25 °C to +55 °C or beyond) and they support tens of thousands of switching cycles.

Procurement teams often compare response sensitivity (e.g. 30 mA, 100 mA, 300 mA in RCD side) and total breaking capacity. The modular approach means replacing or expanding protection later is fast and eliminates full rework of busbars or panel assemblies.

ETI Miniature Breakers & Compact Modules

For spaces with tight footprint constraints—such as control cabinets, lighting circuits, or secondary distribution boards—eti miniature breakers offer protection in the smallest package. Their advantages include lower insertion depth, reduced thermal stress, and compatibility with auxiliary modules (e.g. signal contacts, shunt trips). Many models include optional add-ons like PS KZS-2M/4M auxiliary switches for remote signaling of RCBOs.

These miniature modules maintain mechanical stability under vibration, and their consistent geometry (module width, clipping, terminal spacing) makes panel standardization simpler across system variants.

Compatibility and Integration Notes

All ETI DIN modular devices are compatible with standard 35 mm DIN rails and fit into typical modular enclosures. The modular blocks have keyed mechanical interlocks and uniform spacing to match typical busbar systems. Modules from ETI are designed to be interoperable with their surge protection (ETITEC) and switching accessories (ETISWITCH) within modular distribution boards.

Terminal types (screw, cage clamp, push-in) and labeling schemes remain consistent across product families, easing installation and future replacement. This compatibility is critical in multi-brand panels or service environments, reducing errors during maintenance.

Technical and Safety Standards

ETI electrical protection devices adhere to international norms including IEC 60898, EN 60947, and RoHS. Their insulation systems are rated for 500 V or more, impulse withstand often ≥ 4 kV, and protection degrees vary (IP20 standard, higher in enclosed panels). Housing materials are typically self-extinguishing plastics (e.g. UL 94 V-0). Devices are tested under thermal, dielectric, and short-circuit conditions per batch, ensuring conformity.

Mechanical endurance is regularly rated at tens of thousands of operations. Traceability via batch codes, MPNs, and EAN ensures auditability for system integrators and procurement audits.

Where ETI Breakers & DIN Modular Devices Are Used

eti electrical protection devices find use in numerous sectors:

• Industrial switchboards and local distribution panels.
• Commercial building power distribution and lighting circuits.
• Automation control cabinets and machine feed circuits.
• Photovoltaic or battery energy storage systems (modular protection is especially useful in those layouts).
• Infrastructure, data centers, telecom shelter installations.

Engineers typically evaluate panel layout, load curves, selectivity, redundancy strategy, and expansion plan before specifying ETI modules

How to Select the Right ETI Device

1. Define circuit parameters: rated current, voltage, short-circuit fault current.
2. Pick device type: MCB, RCCB, RCBO, depending on whether overcurrent, residual current, or combined protection is needed.
3. Choose tripping characteristics: B, C, D curves, time-delay, selective types if coordinating multiple layers.
4. Check module width and backbone design: ensure enough space and busbar compatibility.
5. Consider environmental constraints: temperature, humidity, vibration, dust.
6. Procurement constraints: order in packaging multiples, align part codes, avoid mixing revisions.

A common error is mismatching breaking capacity with fault level, or using improper tripping curve for inductive loads — such mis-specifications lead to nuisance trips or under-protection.
